There is no difference. The operations these kernels use are all well-defined and work identically on all CPUs that implement them. In general, FP/SIMD is not nearly as much of a crapshoot as people seem to expect it to be. Beyond timings, there are generally no user-space visible differences in operation between any AVX/SSE instructions in Intel/AMD cpus.
